I'd like to suggest the ability to link a Vault to one or more Firefox containers or Chrome Profiles.

This would be an improvement for people who use multiple logins for the same site, especially for work and personal usage.

This would not limit the selection, but would set the default. For instance, if you link your Vault "Work" to your Firefox container "Work" and you have two github accounts "Work" and "Personal", the "work" account would be the default for login and 2FA while using the "Work" container, and new passwords would be saved in the "Work" vault by default while in this container.

For Chrome Profiles, a similar deal - basically set a default vault so, if you are using the browser addon for two Chome Profiles, it picks the defaults you want it to for saving and pulling login in, 2FA codes, etc.
